SMUT-MACH INE.

Specification of Letters Batent N0. 12,839, dated May 8, 1855.

To all whom it may concern:

Be it known that-I, GRANT B. TURNER, of Cuyahoga F alls,;in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Smut-Machines; and I do hereby declare thefollowing to be a full, clear, and eXact description of the same, reference being had to the accompanying drawings, making a part thereof, in which-- I,

Flgure 1, represents a central vertical section through the entireapparatus, and Figs.

2 and 3, detached portions whichwill be referred to. i

-3 centrator, for separating and removingthe Similar letters in the figures denote like parts.

Thenature of my invention consists first in interposing between the runners, and outer concentrators or the machine, a perforated. flange, which 1 term a partial consmut without allowing it to commingle with the grain after it is once loosened from it. And also, in the method of escapingthe white caps andother lighter material from the screen in the Wind trunk to prevent their choking the screen.

To enable others skilled in the art to make and use my invention, I will proceed to describe the operation of the machine in connection with. the drawing, which will also illustrate the construction. l The grain to be divested of the smut is thrown into the hopper A, which has a slide y y 3 B, in it to regulate the quantity admitted. Motion is communicated to the machine, and the grain falls first on the screen G, which receives a. shaking motion from the cam D,

and spring E, said cam revolving with the shaft F. The grain being separated from man of its impurities on the screen C, drops through the screen onto the inclined board g, the heavier impurities passing oil? at the end of the screen. The grain passes from g, onto the screen H in the wind trunk T,

where it issubjected toa blast from the fan blower, K, near the bottom of'themachine the light impurities separated at this point passing OE and out of the machine at 79, while the heavy grain passesthrough M into the scouring apparatus,.andthellghter grain passes through the screen, andfalling upon the projecting portion T, of the trunk, is

y thrown overand drops out at L. Theheavy the opening grain passing through M, drops through onto the scouring disk or against the cap R, which is also provided on its under side wit-h radial ribs (as seen in Fig. 2) to catch and throw back any grains which may rebound or be cast against it by the rapid motion of the runner. Fro-1n the scourer the grain falls upon the partial concentrator S, the smut passing through its perforations, whence it is carried out by the blast passing through between the inner concentrator S, and the outer one m, and thus a separation of the smut from the grain is made as soon as the smut is loosened from the grain and I would remark that although the main portion of the blast is through the wind trunk, yet enough for the purpose finds its way through the more circuitous passages of the machine. The grain from the last mentioned point passes through another securing and separating apparatus in every respect the same as that just above described, where its entire separation from the smut is effected; it then passes down over the inclined board 1", where it meets considerable of a blast, which carries, what impurities it takes up, out at s. \Vhen the grain arrives at the end of the board a", it meets the whole blast from the fan blower, and the heavy particles only pass through the blast, and out at a, while thelight wheat, white caps, &c., are carried up the trunk T, by the blast, the light wheat strikes against the underside of the projection T, in the trunk, and its motion being checked and thrown over or out of the blast it finally passes out at L. The white caps, of which some will always follow the grain, are blown Q, is the shaft on which the runners are hung and which is driven by a belt or band passing around a pulley thereon.

N is the frame on which" the machine is supported. v

Having thus fully described the nature of my invention what I claim therein as new and desire to secure by Letters Patent is 1. In combination with the scouring disk or runner and outside concentrator, the the scouring plates to pass out, instead of inner perforated and partial concentrator, being held up against the bottom of said slightly elevated from the outerfone, for the screen by the blast, as set forth.

urpose and in the manner set orth. T p 2. I also claim in combination with the GRALT TURNER screen H in the blast trunk T, the opening Witnesses: 24 directly under said screen to allow the A. B. STOUGHTON, white caps which may have passed through THos. H. UEPPERMAN.
